The distinct parallel ridges of the Pennsylvania coal region define the landscape in this 1977 orthophotographic study. Line Mountain, Mahantango Mountain, and Broad Mountain form the physical backbone of the terrain, sandwiching narrow valleys where agriculture and industry coexist. This aerial perspective, produced by the Geological Survey and the Soil Conservation Service, reveals the intricate land-use patterns in the valley between Hegins and Fountain.
